Your grade in the class consists of 2 midterms 15% each, homework 10%, projects 5%, attendance 10%, and final 30%. Find the weighted mean if your
scores are as follows in the class.
Midterm 1:85
Midterm 2:90
Final : 80
Homework: 95
Project : 100
Attendace : 75
What is the sum of the weights that is find w =?

b is the correct answer

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
